deltaTimeAndReset()

DeltaTime LUPI::Timer::deltaTimeAndReset

(

)

Calls deltaTime and then reset. Returns the results of the call to deltaTime.

Returns

A DeltaTime representing the time since this was created or reset was called.

    DeltaTime deltaTime1 = deltaTime( );
    reset( );
 
    return( deltaTime1 );
}

reset()

void LUPI::Timer::reset

(

)

Resets the internal times to the current time.
